Performance research on piezoelectric pumps based on holistic opening valve and cantilever valve
The flow performance characteristics of two check valves
the holistic opening valve and the cantilever valve
were investigated. The prototype of piezoelectric pump with double series-wound chambers was manufactured in two form valves. The experimental results show that the self-suck ability and output flux of the piezoelectric pump with holistic opening valve are better than the piezoelectric pump with cantilever valve. With the alternating current of 200 V
the maximum self-suck height of the formers is 430 mm water column (the pressure is about 43 kPa)
and the maximum output flux is 972 ml/min
the counterpart value of the latter piezoelectric pump is 410 water column and 480 ml/min
respectively.
